Emotions as value experiences
The dominant view in philosophy of emotion - the evaluative theory - holds that emotions are ways of representing value. Fear presents something as dangerous; grief presents something as a tragic loss; joy presents something as good. Emotions don't just happen in the void. They depend on prior or simultaneous mental states that specify the object of the emotion. These are the cognitive bases.
For example, you don't just feel fear in the abstract. You're walking down a dim street and a dog lunges at the fence. You see the flash of its bared teeth, hear the low, guttural growl vibrating in your chest, and catch the quick snap of movement as it surges forward. Each perception on its own could be innocuous - teeth, sound, motion. But together, they form the cognitive base that your mind fuses into a single evaluative reality: this is dangerous, I need to get away. The emotion of fear isn't a bolt from nowhere; it's the product of disparate fragments unified into value.
Why bases matter
Cognitive bases do three things:
- They explain occurrence - seeing the dog helps explain why you feel fear.
- They determine content - the teeth, growl, and posture shape the precise kind of fear you feel.
- They affect justification - your fear is rational if the dog really is dangerous, given the evidence provided by the base.
But what makes a base sufficient? Can a scattered set of perceptions really ground a coherent emotion?
The unity condition
Here the paper introduces its central claim: an emotion must be based on a unified representation of the right kind of features. A heap of disconnected impressions won't do. Just as random car parts don't make a car, random perceptions don't automatically constitute fear, grief, or joy.
To count as a cognitive base, the parts must come together as an integrated whole. This is the unity condition. It requires that the features making up an emotion's object be represented in a way that makes their relation to the value clear. In other words, fear of the dog isn't just "teeth + growl + fur" - it's the configuration of those features that amounts to dangerousness.
Without unity, emotions would collapse into arbitrary fragments. With unity, they gain coherence, direction, and intelligibility.
Disunity and confusion
One challenge to the unity condition is that we sometimes feel emotions in moments of mental fragmentation. Don't these count as counterexamples - emotions with disunified cognitive bases?
Take the case of panic in a crowded station. You're jostled by bodies, flashes of noise and movement overwhelm your senses, and for a moment you don't know what you're reacting to. The emotion is raw panic - but is it based on a unified representation? The answer is yes: what you're really feeling is an emotion about the experience of overload itself. Your mind represents the disarray as a single state - confusion, loss of orientation - and panic attaches to that whole. The fragments become unified under the label of being overwhelmed.
Now consider a free-floating sense of guilt. You feel a heaviness in your chest, a vague conviction that you've done something wrong, but the details escape you. Hours later, you recall the sharp comment you made to a friend the night before and realize: that was the source. At first glance, the guilt seemed to exist without a unified base. But in fact, your mind was already tracking a cluster of features - the dissonance between your self-image and your behavior, the lingering memory of tension - and representing them as a single, if blurry, evaluative whole. The emotion came first, but it served as the glue that eventually organized the fragments into clarity.
Or take nostalgia triggered by a scent. You smell baking bread and feel an aching longing, yet you can't place why. Only later do you remember afternoons in your grandmother's kitchen. The emotion of nostalgia is not disunified; it is a unified feeling about a hazy object - a past worth yearning for. Even when the particulars lag behind, the unity of the value is already there.
The same logic applies in positive cases. Imagine standing in a forest clearing at sunrise. At first, the details are separate: the chill of the air, the glow of light between trees, the sudden trill of birdsong. Slowly, they converge into a single, powerful sense of wonder. What begins as a series of scattered impressions fuses into the value of beauty, presence, or awe. Here again, the emotion depends on a unified base: it is the integration of those fragments that makes wonder possible.
These cases show that apparent disunity is rarely true disunity. What looks like a scattered set of impressions is typically held together by a tacit, if incomplete, unity. Emotions may begin vague, or grow clearer over time, but they still presuppose some minimal unifying frame. Without that frame, there would be no emotion at all - just fragments of sensation without value. This is precisely why the unity condition holds: even when our minds are clouded or fragmented, emotions still rely on some hidden structure that binds their bases together into a coherent experience of value.
Why it matters
If the unity condition holds, the evaluative theory of emotion rests on solid ground: emotions are not just raw feelings but structured representations of value. This makes them potential sources of knowledge, not just impulses. But it also raises the bar: to defend the theory, philosophers must defend the idea that every genuine emotion depends on some kind of unified base.
Closing reflection
The argument shifts how we think about emotional life. Emotions are not arbitrary eruptions; they are structured acts of synthesis. They gather features of the world, unify them, and reveal them as value. The snarling dog is presented as dangerous, the reunion as precious, the failure as shameful. Each emotion is a miniature act of structuring - and without unity, the very possibility of value in experience would unravel.
